This is image is the modern theory of what atoms look like. The protons are positive, the neutrons are negative, and the electrons are negative. The protons and the neutrons are much larger than electrons and are located int he center of the atom in the nucleus. The electons which are much smaller are traveling in beehive orbits around the nucleus. The nucleus is trillion times smaller than entire atom.
The modern atomic theory as taken two million years to evolve into what it is today. It wasn't until the end of the 19 century that technology became advanced enough to allow scientist to get a glimise of atoms and its parts: electrons, protons, and neutrons. Some of the scientists that contributed to the theory were Schroedinger, Einstein, Luis De Broglie, Max Planck, Frank Hertz, Maxwell, and Fermi. The current model was created by a complexity of math equations and the relationship between wave lengths (quantum physics model).
Some of the short comings of the model is that the electrons have different lengths and sizes and like any other atomic model, you are not totally sure it is correct. Throughout history, theories about the atom and what it looks like have been proven true and then later changed into something more accurate. Like any atom theory, the modern one cannot be totally proven true because scientists have not actually seen this model. They have just done test and series of math equations that enable them to give a very educated hypothesis on what the atom looks like.
